HOW DO I DOWNLOAD WAMP

I suggest that you go directly to the source.

English: https://www.wampserver.com/en/
French: https://www.wampserver.com/

Click on “Download” in the menu at the top.

Select the same version as your Windows installation. If you have a 64 bit Windows, select 64 bit Wamp.

If you are unsure of what version you use, I show you how to find out here:
